GEORGE IIELLIAR COLLEY, OF JACKSON, MICHIGAN, ASSIGNOR TO THE IVEEKSCOLLEY MANUFACTURING COMPANY, OF SAME PLACE.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 549,184, dated November5, 1895.

Application filed July 10, 1894.

To all whom it may concern.-

Be it known that I, GEORGE HELLIAR COL- LEY, a citizen of the UnitedStates, residing at Jackson, in the county of Jackson and State ofMichigan, have invented certain new and useful Improvements inSewing-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to sewing-machines, but more particularly totwo-needle or multiple-needle machines of the rotating-shuttle type,such as disclosed in the Letters Patent granted to me November 14, 1893,No. 508,600.

The invention will first be hereinafter more particularly described withreference to the accompanying drawings, and then pointed out in theclaims at the end of the description.

Referring to the accompanying drawings, forming'a part of thisspecification, Figure 1 represents a front view of a shuttle-race and somuch of a sewing-machine as is necessary to illustrate the invention.Fig. 2 is a side view of the shuttle-race with the needles and holderarranged above same. Fig. 3 is a sectional plan View on the line III IIIof Fig. 2, and Fig. 4 is a sectional view on the line IV IV of Fig. 3.

In the drawings, A denotes the work-plate of the sewing-machine; B, theoverhangingarm of the frame or goose-neck which supports and guides theneedle-bar O and pressure-foot bar D.

c c are the needles arranged upon an arm or needle-holder having theusual needlesockets and socketed head to receive the needle-bar andprovided with a lateral extension 0*, so as to set the needles carriedthereby in line with the needles in the usual needlesockets. Securedupon said extension 0 by the set-screws 0 are the sliding clips 0 0having sockets and set-screws, as shown, for the attachment of theneedles. D is the pressure-foot bar, and d the pressure-foot carried bysaid bar.

The parts as thus far described are of the usual or well-knownconstruction in rotatingshuttle machines and may be operated in theusual way, or they are such as disclosed in Serial Nb. 517,046. (Nomodel.)

my aforesaid patent, and therefore further description thereof herein isnot deemed necessary.

E is the raceway arranged below the needle-holder C in any suitablemanner, and preferably consists of separate circular sections E and Ethough this number may be varied, if desired. The section E isstationaryand may be of the ordinary construction, but is preferably ofthe improved form shown and is provided with studs 6 and e, on which thesection E is adjustably held. These studs have one'end of each securedto the section E and the other ends passed through apertures in thesection E on which the said sections are slidingly held. The stud 6 maybe provided with a head 6 on the outer end thereof to limit the movementof the section E the said section carrying a set-screw 6 adapted toengage said stud and by which the section may be adjusted and held inthe proper position. Each section is preferably provided with two races6 and e and has on the outer surface thereof a plate 6 which serves toretain the shuttles in the races 6 The inner portion of each section isprovided with a circumferential recess or slot to receive a segment .G,the said segment being pivotally secured in said circumferential slot bythe pins or screws g and each provided with a circumferential slot orguide-groove g in its inner curved surface, which coincides with thegroove 6 to form a supplementary race in said section. The segment G maybe thrown downwardly on its pivot by the knob or button g secured tosaid segment, as shown in dotted lines in Figs. 2 and 3. Each segment isheld in a raised position by a sliding pin 1 or plunger h engaging anaperture 9 of said segment. This plunger is held within a sleeve h,which is secured to and extends outwardly from the section. The plungeris normally pressed inwardly by a spring 7L surrounding the stem of theplunger 7; and arranged within the sleeve It. On the sleeve is arrangeda projection or pin 7L3 engaging a slot h of the handle 7L To remove theshuttle from or insert a shuttle into one of the races having the hingedsegment, the operator, by pulling the plunger h against the tension ofthe spring h and disengaging it from the aperture of the segment, willpermit said segment to be thrown on its pivot, as shown in dotted linesin Figs. 2 and 3, by a downward pull upon the knob or butten 9 Theplunger may be retained in a disengaged position by simply pulling thesame outwardly by its handle and then slightly turning said handle, soas to prevent the slot 7L from registering with the pin it shown indotted lines in Fig. 3. After the insertion or removal of the shuttlethe segment may be raised and the handle turned to its normal position,at which time the pin 7L3 and slot 7% will register, when the recoil ofthe spring 71,

will throw the end of said plunger into engagement with the aperture ofsaid segment, thereby rigidly holding the same.

I desire to have it understood that I do not wish to confine myself tothe exact construction shown and may vary same in some instances withoutdeparting from the spiritof section so as to form a supplementary race,

and means for opening and closing said segment to permit the insertionor removal of an additional shuttle,substantially as described.

2. In a rotating shuttle sewing machine, the combination of a multipleshuttle-race co1nprising a stationary and an adjustable section, thelatter being provided with a circumferential slot, a segment fittingsaid slot provided with a guide-groove coinciding with a groove in saidsection to form a supplementary race, and means carried by said sectionfor opening and closing said race to permit the insertion or removal ofan additional shuttle, together witha needle-bar and the needleholdersupporting the adjustable needle-sockets, and means for securing thelatter in various positions, substantially as described.

3. In a rotating shuttle sewing machine, a multiple race comprising twoor more sections adjustable with relation to each other and providedwith .a pluralityof interior circular guide'grooves or races, eachsection having a circumferential slot, a segment fitting said slot andprovided with a guide-groove coinciding with a groove in the section soas to form a supplementary race, and means carried by said section forsecuring the segment in said circumferential slot, substantially asdescribed.

4. In a rotating shuttle sewing machine, a multiple race comprising twoor more sections adjustable with relation toeach other and provided witha plurality of interior circular guide-grooves or races and with acircumferential slot, a hinged segment fitting said slot and providedwith a guide-groove coinciding with a groovein the section so as to forma supplementary race, and a spring: pressed pin carried by the sectionfor lockin g said segment within the slot, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE l-IELLIAR OOLLEY.
